1 Claim. 1

This invention relates to a window stop which may be readily mounted ina window sash or other similar structure by inserting it into anaperture drilled to receive such window stop, and more particularly to aspring-actuated window stop for selective engagement in a recess formedin a window frame or like structure.

An object of this invention is to provide a spring actuated window stopadapted to be secured in a window sash or like structure which isprovided with spring means continuously urging the window stop intoengagement with the window frame.

A further object of the invention resides in the provision of a windowstop for locking a window sash within a window frame, which window sashmay not be readily tampered with from the outside of the window.

Another object of the invention resides in the provision of a windowstop which will positively look a window sash in a given positionrelative to a window frame.

Still further objects of the invention reside in the provision of awindow stop that has parts that can be readily manufactured at low costand which may be easily assembled to produce a device that is strong,durable, highly efficient in operation, and capable of being made from avariety of materials.

These, together with the various ancillary objects of the inventionwhich will become apparent as the following description proceeds, areattained by this window stop, a preferred embodiment of which has beenillustrated by way of example only, in the accompanying drawings,wherein:

Figure 1 is a front elevational view of the invention shown in operativeemplacement in a window sash, with parts thereof being broken away toshow the window stop in greater detail;

Figure 2 is a horizontal sectional view as taken along the line 2-2 inFigure 1; and

Figure 3 is an exploded view of two elements used in the window stopcomprising the present invention.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral l generally designates a window sash or like structurewhich is slidably mounted within a window frame [2 having a plurality ofrecesses l4 suitably spaced therein for reception of a stop portion l6of the window stop comprising the present invention. The stop portion Itis formed integral with or connected to f {UNI-TED! STATES PATENT OFFICEa shaft I8 of reduced cross sectional area which is slidable within ahollow sleeve 20 inserted, in an aperture 22 in the window sash [0.

The sleeve 20 is provided with an apertured end wall 24. Adjacent theend wall 24 are a plurality of notches 26 which are individuallyselectively engaged between the bifurcated portions 28 of a bracket 38of substantially L-shape cross section. The bracket 30 is connected tothe sash ill by means of screws 32 inserted through apertures 34 in theside 36 of the bracket 30 opposed to the bifurcated portions 28. Aspring 38 concentric with the shaft I8 is positioned within the sleeve20 and biases the stop portion l6 against the frame [2 and therefor therecesses l4. In threaded engagement with the end of the shaft l8 as at48 is a knurled knob member 42 which limits the outermost position thatthe stop portion 16 may attain.

Unlike other devices, this window stop has a great advantage in theinstallation. As prior art window stops of necessity had to be insertedin the outside of the window frame into a hole drilled in the frame, itwas necessary to remove part of the window casing and take the windowsash out of the frame in order to insert the prior art window stop.

The present invention does not require removal of the window sash. Allthat need be required is to drill a hole through the window sash whilethe window is in situ. The spring 38 is inserted into the sleeve 20 andthe shaft is is then inserted into the sleeve 20 within the spring 38.Then the stop portion I6 is positioned within a recess I4 which has beendrilled into the window frame I2 through aperture 22. The bracket 30 isthen secured to the window sash with the bifurcated prongs 28 inengagement with the notches 28 in the sleeve 20. The bracket 30 thusholds the stop in position.

Since from the foregoing the construction and advantages of this windowstop are readily apparent further description is believed to beunnecessary.

However, since numerous modifications will readily occur to thoseskilled in the art after a consideration of the foregoing specificationand accompanying drawings, it is not intended to limit the invention tothe precise embodiment shown and described, but all suitablemodifications and equivalents may be resorted to which fall within thescope of the appended claim.

Having described the invention, what I claim as new is:

A window stop for locking a window sash to a window frame comprising acylindrical sleeve having an apertured end and adapted to be inserted inan aperture in said sash, a spring projected shaft in said sleeve havingan end slidably extending out of said apertured end and its other endadapted to be projected into an aperture in said frame, a knob on thefirst named 4 REFERENCES CITED The following references are of record inthe file of this patent:
